Definitions

  • This invention relates to a universal type of case structure for angle drive units in generic agricultural machinery.
  • angle drive units such as are commonly employed in agricultural machinery, comprise in general a box-like case casting, wherein seats are machined to accommodate the bearings for one of the units' shafts.
  • the other shaft is journalled in bearings accommodated in seats formed directly in a cover which is mounted to the case casting to complete the assembly.
  • a further object of the invention is to provide such a universal type of case structure which can accept high precision tolerance requirements with simplified machining procedures, and can reduce all the production steps involved in the fabrication of the covers.
  • a not unimportant object of the invention is also that of providing a universal type of case structure which can afford a significant reduction in costs along with an improved quality level thereof.
  • a universal type of case structure for angle drive units in generic agricultural machinery characterized in that it comprises a one-piece construction box-like body of substantially parallelepipedal configuration less one face, provided on the faces of said box-like body being regions for the formation of seats adapted to accommodate bearings for an input shaft and at least one output shaft, there being further provided a cover element mountable to close said missing face of the parallelepipedon.
  • a universal type of case structure for angle drive units in generic agricultural machinery comprises a box-like body of one-piece construction, generally indicated by the reference numeral 1, which is advantageously fabricated as a metal casting and has an approximately parallelepipedal configuration.
  • the box-like body 1 has a face missing from its lateral surface, as indicated at 102 , its opposite face having a tang 103 which projects outwardly.
  • the tang 103 has regions defined thereon whereat seats 104 can be machined for accommodating bearings 105 in which an input shaft, generally indicated at 106, is journalled.
  • impressions, indicated at 120 are provided which can also be machined into bearing seats for at least one output shaft, indicated at 130, which, contingent on individual requirements, may be of a throughgoing design, as shown in Figure 6, or alternatively only extend from one face of the case.
  • a cover 140 which is assembled to close the missing face in the surface 102 has no structural functions but merely that of closing the case to prevent seepage of the oil which is normally poured into the case.
  • the two shafts are interconnected by a bevel pinion 141 meshing with a bevel gear 142 keyed to the other of the shafts.
  • the outer surface of the case may be provided with ribs, as indicated at 150, which will serve the dual functions of stiffening the structure and as a heat exchange means to dissipate the heat generated to the outside.
  • Figures 7 and 8 illustrate a further embodiment of this case, which comprises essentially an elongate case 202 of one-piece construction, preferably a cast piece, defining a first chamber 203 and second chamber 204, respectively, said chambers being interconnected and substantially aligned and open at opposite ends, whereat the first chamber is configured to receive a cover element 205.
  • first and second drive shafts Accommodated within the first and second chambers, respectively, are first and second drive shafts, designated with the reference numerals 206 and 207, which may operate as drive and output shafts, respee- tively and which have first and second drive gears keyed respectively thereto, as indicated at 208 and 209.
  • Said gears are mutually meshed bevel gears for transmitting the motion from the first or drive shaft to the second or output shaft; each shaft being supported in bearings, respectively 210a and 210b for the drive shaft, and 211a and 211b for the output shaft, being accommodated in corresponding seats provided on the case interior.
  • a further advantageous feature of the invention resides in the fit of the case to the output shaft, which includes, on the remote side to the gear 209, a keying means comprising a threaded end portion 212 of the shaft 207 which is engaged by a tightening arrangement of conventional design including a nut and cotter pin 213.
  • Such keying means in addition to providing for the locking of the shaft of a tool holder element 214 thereon, apply an axial force which is sequentially split between said tool holder element, and through a spacer ring 215 mounted coaxially with the shaft 207, on the bearings 21.1a and 211b to hold the latter securely in the case 202 and tightly engage with the shaft itself.
  • a tubular spacer element 216 which accommodates the shaft coaxially thereinto; the mount just described, additionally to being extremely simple and economically favorable, also increases the strength of the inventive drive, because it provides a perfect keyed fit of the tool holder element and a correct assembly of the shaft within the case, while avoiding the objectionable nicking action exerted on the shaft by conventional threaded ring nuts or retainer rings.
  • a shaft so designed would require no changes in diameter along its length, thus affording an added degree of economy in manufacture and machining.
  • the same is provided at the chamber 204 with a biconical portion defined, respectively, by a first frustum 220 and second frustum 221 the minor diameters whereof are located, respectively, at the seats 211a and 211b, while their major diameters are located at the connection area between the frusta 220 and 221, whereat the case is formed with a mounting flange 222 externally to the chamber 204.
  • stiffening ribs 223 may also be provided to connect the case to the flange formation.
  • the case has a step formation 225 which extends annularly around it and has a profile mating with one or more steps 226 formed on the tool holder element, thereby a labyrinth 227 is created which is effective to prevent dirt, grass, or other matter from entering the case and contaminate it.
  • the ring spacer 215 provides an engagement surface for a seal ring 228 to be received in the cited lower opening adjacent to the bearing 211b.
  • the invention achieves its objects, and in particular that the universal case structure for angle drive units, according to this invention, affords the faculty of prearranging connections on all of the case faces without having to alter the case structure itself.
  • the inventive structure moreover, enables the use of a throughgoing shaft without involving any of the constructional complexities of prior structures.
  • any materials provided that they are compatible with the specific intended application, and any dimensions and contingent shapes, may be selected, and used to meet ones individual requirements.
